Be it known that I, GEORGE E. SCHUMAN, of Louisville, in the county of Jefferson and- State of Kentucky, have invented certain new and useful Improvements in Calculating-Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the ac-' novel mechanism for arresting or detainingthe registering-le ers when no keys ertaining thereto are depressed, to provir e novel carryover mechanism, to provide a novel total-indicating mechanism, to provide a novel mechanism for indicating the last item recorded until the next is being recorded, so that the operator can always see u on returning-to the machine what was the ast item recorded without having to inspect the printed record, to provide novel printing mechanism for recording the items and totals, to provide a novel type-hammer-locking mechanism, to provide a novel type-alining mechanism, to provide a novel totaling mechanism whereby the totals may he ascertained and printed at any time, to provide a novel mechanism for indicating on the rec ord whenever a total has been taken or the machine reset to zero, to providenovel paper-carriers, to provide novel repeatim mechanism. whereby items may be repeaterv without resetting the keys, and to provide a novel error-key whereby the keys may be released without operating the machine in case an error has been made in depressing the keys.

The invention will be clearly understood from the following description, and the features and combinations of parts embodying the invention for which protection is desired are summarized in the claims following the description of the machine as illustrated in the accompanying drawings, in which-- Figure 1 is a front elevation of the machine with the outer casing hroken away or removed, so as to show the operative parts.

The machine embodies a plurality of adding mechanisms arranged side by side and each constructed substantially alike and arranged, as usual, so that the units-wheel carries over at the tenth unit to the tenswheel and so on up to the total capacity of the machine. There is one set of such mech anisms for each denomination in the decimal notation up to the capacity of the machine, which can be made of any desired capacity by simply adding additional duplicate mechamsms.

The registering mechanism.-The registering-wheels 1 are loosely mounted side by side on a shaft 1", journaled in the sides of the main frame of the machine. Each registering-wheel is constructed with ten teeth-as shown, each has fifty teeth so that for each fifth of a revolution of the Wheel ten numerals of its denomination will be counted and at every fifth of a revolution of a registering-wheel of lower denomination mechanism is actuated to carry over or move the wheel of next higher denomination one tooth.

Loosely mounted on the shaft 1 beside each registering-wheel 1 is a vibrating lever 1 which is thus pivoted beside the wheel and swings in an arc concentric therewith. The levers are thrown backward by springs 1 when the levers are released from control of the resetting-arm, hereinafter described. The springs 1 are conveniently mounted on shaft 1 as shown. The n per end of each lever 1 is provided with a aterally-prOjecting finger1,which moves in an are when the lever is oscillated parallel with and beneath a multiple of Ioo a related row of keys 3, and if any key in such row be depressed it will arrest the backward movement of such lever.

Each lever 1 carries a pawl 1 which is l 5 normally. held in en agementnvith the teeth of the registering-wheel by a spring 1 the pawl being pivoted on a pin or screw 1 attached to the lever. Pivoted on said pin 1 is a second pawll which extends in a direc- 1o tion opposite pawl 1 and itstail engages a so that when one pawl is in engagement with the wheel 1 the other'is out of engagement. Pawl 1 is controlled by a spring 13, hung on a screw 1 with one end bearing on pawl 1 and the other on pin 1, so that the spring l does not oppose the spring 1, which normally holds pawl 1 in engagement with the wheel 1.

v The tail of'pawl 1 projects beyond and so above pawl l and is provided with a pin 1 which at the pro er times is engaged and depin 1 on pawl 1,

pressed by suita le devices, hereinafter ex 5 keyed on shaft 1*, meshes with a segmental ear 2 on a shaft 2, journaled in the main ame parallel with shaft 1. Shaft 2 is provided with a hand-lever 2 on its outer end, by which it can be rocked forwardly; but

' 40 when the lever is released the shaft is rocked backward and normally held in rearmost position by means of a stout spring 2, attached to an arm 2? on shaft 2 and, to a suitable point on the main frame, as shown in Fig. 2. 4,5 As shaft 1 is geared to shaft2, it is obvious that the normal position of shaft 1 is that 1 shown in Fig. 2, with the pushr- 1 holding all the levers 1 in their foremost position. If desired, the return spring-impelled move- 5o ment of shafts 2 and l may be cushioned by v a dash pot 2', attached to an arm 2 on shaft 2 and 'enga ed by a plunger attached to a rod 2?, pivota y, connected to shown in Fig. 2.

5 The keyb0ard.As shown, there are nine keys in each row, (one row'for' each denomination.) These keys 3 are vertically movable, and their stems aremounted in slotted plates 3, attached-to the frame, as shown.

The lower. ends of thefirst eight key-stems are curved'so' that their extremities will coincide with the arc traversed by the finger 1 on the. related lever l and will be equidistant, sothat the space traversed by the lever.

1 in moving from-one key to the next will if the wrong key is depressed and locked the frame, as

. senate jllSl suffice to move the registering-wheel 1 one notch or tooth. Each key is normally upheld by means of a suitable s ring 3*, attached to the key and to a suita le point on the upper plate 3*,as shown in Fig. 2. Each key-stem has a ratchet-tooth 3 ;on its side,

whichwhen the key is depressed catches under a swinging catch-plate 3, hung from the upper slotted plate 3 and normally swung inward toward the stems by a spring 3 so as to look any depressed key until after the registration has been effected, when it is automatically disengaged from the key, as hereinafter described. This plate 3 moreover, prevents more than one key being locked down successively in any one row, and only the last key depressed will remain down, fpr t e operator merely has to push down the right key, which as it descends swings the lockingplate 3 .outward, releasing the previouslydepressed key, while the last-depressed key is held down. Thus if the operator discovers an error in his keyboard before actuating the hand-lever 2? he can instantly correct it by merely depressing the proper keys without having any errors in computation arise. Preferably the stem of the ninth key is short, and when 9 is to be added on any one wheel the lever 1 meets no obstruction in its rearward movement until it strikes a stop-bar 3 which is permanently fastened at the rearmost' limit of movement of the levers 1 and serves as a-common ninth stop for all the levers 1*. I I

The registering-lever detainee-in order to prevent the lever 1 moving rearward when no keys have .been depressed in its related row, although it is released by the rearward movement of the pusher 1 I provide a retamer-finger 3, which is attached to the forward end of the related catchplate 3 and depends just in front of the lever 1 whenthe latter is in foremost position, Fig. 2. When any key in such row is depressed, however, the catch late 3 is swung outward, so

as to move the 'etainer 3 out of the path of finger 1 of the lever 1 and as the catchlate cannot swing back to inactive osition until all the keys are released the etainer remains out of the way until the lever 1 has made its operative oscillation. The detamer '3' is provided with a slanting guard 3, which the lever 1 will engage on its return movement (if the detainer has swung back to operative position) and push the detainer outof the way, so it will not be injured.

The keyre'Zease.-A.fter each registering operation itis necessary to release the keys prior to setting the next item, and this isone as follows, (see Fig. 2:) Arranged at the front of the keyboard and extending ast the forward ends of the several catch-p ates 3* is a slide-bar 49, which is suitably sup.- ported, so that it can be reciprocated longi= strike lever 4 and cause it to move bar 4 so tudinally. This bar has a series of inwardlyprojecting pins 4", which project near the adjacent ends of the catch-plates 3", but lie normally out of contact therewith. Bar 4 (see Fig. 1) is pivotally connected to one arm of a bell-crank lever 4 pivoted on the frame with its free arm lying below the keyboard in position to be struck by the free end of a vibrating lever 4, pivoted at 4 to the side of the frame. Lever 4 has a depending arm 4 which extends downward toward a segmental gear 1 on shaft 1; On the lower end of arm 4 is pivoted a dog 4 which has a tooth. depending beside segment 1 and adapted to be engaged by a pin 1 thereon. When segment 1 rotates backwardly, pin 1 tilts the dog and passes thereunder without oscillating lever 4; but on the return movement of the segment pin 1 engages the dog, and the latter being locked against a stop 4 on arm 4 saidarm is swung forward, raising'lever 4 and causing its upper end to that pins 4" thereon engage the catchplates 3 and swing them-outward or away from the key-stems, thus releasing all the keys. The pin 1 moves forward sufficiently to clear dog 4 whereupon arm 4 and lever 4 are'returned to normal position by a spring 4", and bar 4 is also returned to normal osition by a spring 4.

. Tiih carr-y-0ver.-Alaterallyrojecting )in 1 is attached to the side of eac iwheel 1 a jacent each tenth tooth. (In the drawings there are five such pins 011 each registering-wheel.) This pinis adapted to engage one arm of a bell-crank trip 5 pivoted on a swinging lever 5, hung on shaft 1 besidethe registeringwheel and having its lower end guided in a slotted plate 5 the trip being controlled by a spring 5*. The lower arm of trip 5 lies above a plate 5, loosely mounted on a transverse rod 5*, said plate being upheld by a spring 5", and a tooth 5 on plate 55 engages a notch 5 on a projection of the next adja cent lever 5 pertaining to the wheel of next higher denomination and locks this lever in rearmost position, as indicated in F i s. 2, 3, 4, against the tension of a spring 5 which always tends to swing lever 5 forward. The lever 5 adjacent each wheel of higher denomination carries a pivoted dog 5", which is yieldingly held in engagement with the teeth of such registering-wheel by a spring 5 This dog will trail on the wheelwhen the lever 5 is swung outward, but will move the wheel when the lever is swung inward. Any released. lever 5 will be moved backward at the proper time by means of a bail 5 attached to a rock-shaft 5, which is provided with an arm 5, carrying a dog 5 controlled by a spring 5 (see Fig. 2) said dog proj ecting into the path of a pin 1 on segment 1, so that when said segment is rocked by the forward movement of hand-lever 2 the pin 1 will engage the dog and rock-shalt 5", so as to cause the bail 5" to push the lever 5 rearward until'they are locked In," the engaging plates 5", and on the return movement of the segment the dog \\'|ll yield and allow the pin 1* to pass it without atl'ectiug the shaft 5.

Now when a pin 1" on a wheel 1 of lower denomination engages and aet'uates the related rip 5 said trip depresses the adjrueent cateirplate 5" and causes it to release the lever 5 of the wheel of next higher denomination, whereupon the said lever is thrown forward by its spring 5. Then when the handlever 2 is drawn forward shaft 5 is rocked, as described, and hail 5' pushes the released lever 5 inward sullicieutly to cause its dog 5- to turn its registering-wheel one tooth, and thus effects the carry-over operation. If the wheel of higher denomination just referred to happened to stand at the ninth tooth at. the time its lever 5 was released by the movement of the wheel of lower denomination, oh-

. viously a pin 1" on such wheel would in such case be in the path of the trip 5 on its related lever 5, so that when said lever was swung backward by spring 5 the trip 5 thereon would be rocked by the pin 1 on the srationary wheel and cause the next catch-plate to release the lever 5 of the next wheel of higher denomination, so that when shaft 5 was rocked both wheels of higher denomination would be actuated and the carry-overs effected.

The total indicator. -1 wheel 1 meshes with a small ten-toothed pinon 1, loosely mounted on a shaft 1" in front of the registeringsvheels, and each pinion 1 has a numeral-disk 1, so that by reading the alined numbers on said disk 1' at the sightopening the total amount-added by the registering-wh eels can be ascertained.

The item-inclica tor.Opprisite each registering-wheel 1 is a pinion is, loosely mounted 011 a laterally-movable rod 6, which is supported. on swinging hangers 6 pivoted to the sides of the frame, as at 6. Each pinion 6 is provided with a numeral-disk 6 and said disks and pinions are normally held at zero position by means of a coiled spring 6, one end of which is attached to the disk and the other to an arm 6 on rod 6 which arm 6" also serves as a stop to engage a pin 6 on the disk to arrestthe return movement of the disk at zero position. Rod 6 is moved in position to bring'pinions 6 in mesh with the registering-wheels 1 by means of an arm 6 attached to one of the hangers 6" and extend ing inward toward the segment-1 which seg: ment has a cam portion 1, (see Fig. 2,)which engages the inner end of arm 6 when the segment is rocked by the forward movement of hand-lever 2 and raises said arm, thereby swinging rod 6 inward and causing pinions 6 to mesh with wheels before the latter are ach registeringloo hand-lever 2 as above described. Thus the operator can leave the machine at any time the latter is upheld (during the return'move -ment of-hand-lever 2 and segment 1) by 'means of a finger 5 on shaft5- which drops (seeFig. 2) and re-' is rocked by the.

under a pin 6 on arm 6? mains there until shaft 5 next succeeding forward movement of' the hand-lever 2 The pinion 6 comes into mesh with wheels 1 when the pinions are at zero position andremain in mesh therewith while and after the Wheels are moved toregister. Consequently the number' of teeth each wheelhas moved be shown by its related indicator-disk 6 andbyreading the alined numbers on such at the sightopening or reading-point the amount ofthe last item just taken by the machine will be ascertained. This ,item remains visible until the operator hasgset the keys for the next item and moves handlever 2 forward to register it, whereupon the initial movement of shaft 5' draws finger 5 away from and permitsa'rm 6 to drop,'and rod 6* swings forward, taking the pinions 6 out of mesh with .the registering-wheels, this movement of rod 6 being accelerated by a spring 6 and as soon as pinions 6 are out of mesh with wheels 1 springs 6 throw disks 6 back to zero position. Immediately thereafter. and during the continuance ward movement of hand-lever 2 cam 1 again engages arm 6 and returns the pinions (S -into mesh with the wheels 1 before they are actuated, and they remain in mesh therewith until the nextmitial forward movement of and always can see at a glance what was the last item recorded if he looks before again manipulating hand-lever 2 The printing mechanism.The machine is provided with. mechanism to print-each item added on the machine as follows: Attached to the levers 1 are curved type-carrying bars 7, each of which carries ten type characters, (numerals O to 9, inclusive.) Each type character 7 is radially movable in the bar and is held in position by a spring 7*, which may be threaded through the several type, as shown, and permits each type to be projected outward at the printing point when struck by a ham'mer 7", as hereinafter explained. The type-carriers 7 are arranged close together, so that impressions from the type thereon will be properly related. Each tvpe-hammer 7 is mounted on a lever 7 Figs? 3 and 4, which is loosely pivoted on a shaft 7 and is provided with an arm 7 by which the hammer is cocked, a spring 7 connected to saidv arm and a point on, the frame, being adapted to actuate the hammer. The arms 7 are engaged and moved inward to set the hammers by a push-plate 7 mounted on a bail 7 attached to shaft 7 plate 7 lying behind arms '7? and being normally held by a spring 7 of the fore.

that when 'bail 7 is swung inward plate .7 will engage arms 7 and push them inward,

at suchan angle setting the hammers against the resistance .T

of springs 7 After the type are'in position to print plate 7 which continues tomove' inward, is tripped by-means of a finger-7 en'' gaging a stop 7, Figs. 3 and i, andpcaused to release arms 7, throw the hammers against the type, and the pression on the paper carried by the pa ercarriage, hereinafter described. 's aft 7 is rocked at the proper time, so. as to move plate 7 as described, by means of a crankarm 7, connected by a link 7 with apin 7 on segment 2 (See Fig. 2.) I

The type-alining device-Above shaft 7 e is a shaft 7 on which are arms 7 that extend toward the hammers 7, but terminate below the tops thereof. To these arms 7 s is pivoted a bail-shaped bar 7, which is adapted to come underneath a row of alined types, preferably in a row beneath those at the printin -point, and is then rocked so as to engage suc types and bring them into exact alinement, so that The the printed record will appear perfects, bail 7 is moved rearward after the type-car'- 'riers have come to rest ready for the printing operation bymeans of a cam-slot 7 in a plate 7 attached to shaft 7 and actuated thereby, said slot 7 being engaged by a pin 7 ,,attached to shaft 7', so as to impart a proper rocking -motion to shaft 7 at the proper time and then hold said shaft momen tarily at rest,,a suitable dwell bein provided in slot 7 for this purpose.

whereupon springs 7 'latter are forced outwardand make an im- VVhi e bail 7 is thus held in its rearmost position a forwardly-extending finger 7, on thebail is engaged by the pusher 1 which at the moment is moving to itsrearmostposition,

and

bail 7 is elevated slightlv'so as to engage the during the alining operation, if such carrier has'not been displaced.

The type-hammer lock. vent the hammers printing ciphers to the left in cases where wheels of higher den0nii nation have not been moved, I rovide devices for locking such hammers w en cocked,

as follows: On a bar 8, in front of and slightly above the hammers, is a slide 8*, which is provided with a depending part 8 that is adapted to pass in rear of the upperends of the hammers after they are cocked and will prevent the hammers sprin ing back when released by plate 7 As on y the left-hand as described, and hold them rnomen- In order to, aline the 0 type on seems hammers should be locked, the inward movement. of slide 8 is automatically controlled by the type-carriers, said plate being provided with a bayonet-shaped linger 8 which projects in rear of the hammers (see Fig. and is adapted to contact with the type-carrier of the wheel of highest denomination that has been shifted and arrest the slide, so that it only looks the hammers to the left of such carrier. Consequently when plate 7 disengages the arms 7 the hammers locked (when stem 10 is depressed) to ens by slide 8 will not actuatethe type, while the other hammers will operate as above described. Then after bail 7 t has returned to its normal position, Fig. 4, the slide 8? is moved back .out of the way, sees not to interfere with the next setting operation of the hammers, and the released hammers fly back, but are arrested by bail 7 before they can engage the type. Slide 8 ismoved inward at the proper time by means of a link 8 connected to an arm 8' on a vertical rock-shaft 8 .a spring 8 drawing the slide inward (when permitted) until it isarrested by? iinger 8, striking type-carrier, as above explained. The slide is positively moved out of the way at the proper time and held out of i the way until the plate 7 cooks the hammers by means of a pin S on shaft 8 which is engaged by a catch 8* on arm 7", attached to shaft 7*, sothat when shaft 7 is rocked backward slide 8*is moved to the left clear of "the hammers. Shaft 7 e returns before slide 8 should be released. Consequently a bell-orank-shaped detent' 8 is pivoted beside shaft 8 in .position to drop in'front of pin 8 and lock the latter in the position to which it has been drawn by catch 8* (see Fig. 2) and hold it while shaft 7"- and catch 8" rock forward and. until a pin 8 on link 7 strikes the upstanding arm of the detent and causes it to disengage pin 8 whereupon spring 8 throws the slide into lockin position until it is arrested by finger 8 stri ing a type-can rier, as indicated in Fig. 5.

The totaling mechanism- 111 order toprint the total amount which" has been added'at any time, I provide the following devices.

(See Fig. 3.) A key-stem 10 is arranged at one side of the machine and is pivotally cohnected at its lower and teen arm .10 on a shaft 10", which shafthas a series of fingers 10 extending inwardly and normally overlying the pawls 5 (see'Fig. 4,) so that when the key is depressed said fingers will disengage said pawls 1 from the wheels 1. The

stem 10 is also pivotally connected to an array 10 on a shaft 10*, Fig; 3, to which isattached a series of curved arms 10", which extend over the pawls i and are adapted pins 1 on the tails of pawls 1 and throw s1 a;

out of engagementwith wheels land atsame time cause pawls 1 to engage with said wheels, thev arms lO 'being'long enough to be hel printed. is loosely mounted a type-lever 17, carrying "on its upper end a single type character 17,

preferably an asterisk or other peculiar char acter, which lies in position to print on the awls hold the pawls in this condition during the entire movement of levers l the pawls 1 trailing under the curved arms. Arm 10 is connected by a link 10 with a bell-crank 10 pivotally connected to the bar 4 so that when arm 10 is depressed said bar 4 is shifted so as to swing'the catch-plates 3 and move detents 3 out of the way of levers 1 and hold. them so as long as key 10 is depressed. -On' shaft 10* is a pin 10 Fig. 2, which is adapted to engage a lug 5 on shaft 5 and rock said shaft, so as to disengage finger 5 and allow rod 6 to swing pinions 6 out of mesh with the wheels 1, as above described. All these operations being performed on the depression of stem. 10, the operator then draws hand-lever 2 forward, freeing levers from pin 6 l from pusher 1 whereupon the said levers 1 are thrown backward by their individual springs, and as pawls 1 are then in mesh with wheels 1 said wheels will be rotated backward until their pins 1 come against the rear side of the trip 5 Fig. 4, whereby the wheels are arrested with the small wheels at O, and the proper type will then be arrested at the printing-point, and. the total is printed immediately thereafter before the hand-lever completes its 'forward stroke. If the stem 10 be held down. while the hand-lever 2 is makin its return stroke, the numeral-disks 1 wil. remain reset to zero; but: if. the stem 10 be released before the-handlever is returned pawls 1' will engage the wheels 1, and the wheels 1 and the numerahdisks will assume the same positions they had before er lil on the rearwardly-extendingarm of lever 10 and effectively preventing depression or release of the totahkey stem 10 at the wrong time. 1

' The Tinted-zero *indt'caion-Jf the stem. 10 (l down during the entire totaling oporation and. the machine reset to zero, the

fact will be automatically indicated 'on the printed record by the following mechanism when theiirst item in a new transaction is On the shaft 7 beside the ball 7 paper alined with the other type at any print ng operation when said type-lever 17 is permitted to operate aTlllS lever 171s controlled by a spring 1? The lower end of ITO path .of pin 17; butthe lever projects below the shaft 7, .and on this lower end is a pin 17, which normally 3 contacts with one of the members ofbail 7 which rocks the lever 17 as it' vibrates and ordinarily keeps the t e-lever 17 from printing. Below lever 17, ut adjacent its lower end, is a bell-crank catch-lever 17, pivoted.

on a stud 17 and controlled by a spring 17*. One arm of this lever projectstoward pin- 17 and is adapted, if raised, to engage said pin. and prevent the lever 17 returning to normal position after being moved backward by bail 7 The lever 17 normally lies below the it is connected by a spring 17 and link 17 to an arm-17 on s aft 10*, so that when the stem 10 is de pressed the lever 17 is lifted against pin 17 placing spring 17 under tension, and when bail 7 is drawn forward the pin 17 will move down, allowing the catch-lever 17 to be drawn forward by spring 17*, so that if the total-key is held down during the entire oscillating movement of hand-lever 2 the catch-lever 17 will remain in frontof pin 17 in position to engage said pin and to lock lever 17 when total-key is released, (see Fig. 4 but at the next printing operation of the machine, (preceding which plate 7 is swung inward to cock the typehammers,) as above key is released such po 7 rollers 9 9 and 9 mounted, on

,m a transverse plate described, about the time that plate 7 is tripped to release the type-hammers the lever 17 is tripped, so as to release type-lever 17 and allow it to make an impression on the paper, lever 17 being tripped at the proper time by means of a finger 17 on bail 7 (See Figs/4 and 4 The asterisk or character printed b lever 17 will denote unmistakably on the record that a total had just previously been printed and that the numeraldisks 1 had been reset to zero. If the totalat end of forward movement (as in taking subtotals,) the catch-lever 17 will drop back to normal position and will not lock lever 17, and at the next printing operation of machine type-lever 17 will not make an impression on the paper.

r The paper-carrier.-At the rear of the machine is a platen-roller 9 and coacting feed- 9 which are journaled in brackets a frame 9, which frame is slidably supported on a rod 9, attached to themain frame, (See Fig. 3.) The laten-frame 9 is provided with a rearwardl'y extending finger 9 which can be enaged with any one of a series of notches 9 9, attached to the main frame, and whichwill hold the carriage in any position to which it is adjusted by hand, the platen-carriage being raised or tilted by hand so as to disengage finger 9 from any notch and then the carriage moved right or left until the finger is under the desired notch, when the carriage maybe released and remains in 'tion until again 3 'fted by hand, The

of hand-lever,

are vieldingly up held by springs 9.

platen-roller 9 is provided with the usual finger manipulating-button 9 on one end, also with a ratchet 9, which is engaged by a pawl 9, pivotallymounted on a swinging plate 9', to which is. attached a longitudinally-disposed bar 9", that extends the length of the roller. 9 \Vhe n the platen-carriage is lowered, this bar 9" lies in front of an oscillating lever 9, which is loosely mounted on shaft 7" and vibrated by means of a link 9?, attached to arm 5.on the shaft 5. (See Fig. 2.) Lever 9 oscillates bar 9, so as to rotate platen 4 9 and turn the paper forward one line after The bar 9" may each printing operation. be retracted by a spring 9 By this construetion a series of columns may be printed on, the same sheet of paper at successive operations, the paper-carriage being shifted by hand from one notch 9 to another after each column is finished.

The inking-ribbon is passed between the type and platen, as indicated in Figs. 2 and 3. Preferably I employ a two-color ribbon, and the ribbon-spools rotatable rods 9-, (see Fig. 5,) which spools The rods have ratchets 9 on their lower ends engaged by oscillating dogs 9, which are shifted by any suitable means so as to enable the ribbon to be wound or unwound from one spool to the other at will. The ordinaryitemprinting may be done on the lower side of the ribbon, which, for example, may be blue, while the total and subtotal printing Ina be efiected from the upper part of the rib on, which is, for example, red. In order to shift the ribbon-spools at the proper time, curved lingers 10 are attached to shaft 10 and when the total-key is depressed, as above explained, said lingers 10 contact with and dc- 9 are slidably keyed on press the ribbon-spools O so that the red held there while thetotal'or subj IIO stem 14 of which normally lies just above I v the tail of the trip pawl 4 on the arm 4* of key-release lever 4. When key 14 is depressed, its stem engages the tail of dog 4 (see Fig. 2) and will hold said dog out of the path of pin 1 so that the key-release lever 4; will not be operated, and the item may be printed a number of times in succession by holding key 14 down and oscillating hand-lever 2", as above described. Stem 1 1 may be provided with anotch 14", which can be engaged with the upper guide-plate to lock the key depressed by simply pushing the key rearward extension 4 14 to one side after it is depressed. When the key 14 is released, it is thrown upward by a spring 1 1 and remains out of the way, and the lever 4 then causes the release of the keys, as above described.

Errorlcey.lf at any time the operator should set up a wrong item on the keyboard and discover his error before can correct it by depressing a key 13, whose stem 13 extends into close proximity to a of lever 4, (see Fig. 2,) and by depressing this key lever 4 is oscillated and'caused to shift release-bar and all the keys are released and may be reset.

Abnormal movement or casual displacement of the wheels 1 is prevented by frictional pawls 12, actuated by s rings 12 I do not limit myself to details of construction as shown, as these may be modified in many particulars Without departing from the spirit of my invention.
